Use the atm pvc command to create a PVC on the Catalyst 5000 family and 2926G series switch interface. The no form of this command deletes the specified PVC.
|
Note The following version of the atm pvc command is available only in ATM software release 50.1(1) and later and 51.1(1) and later. |
|
Note The following version of the atm pvc command is available only in ATM software release 11.3(6)WA4(9b) and later. |
Syntax Description
| 1The minimum pcr rate is 64 kbps. If you specify a pcr greater than 0 and less than 64 kbps, the rate specified to the SAR is 64 kbps.
2The minimum scr rate is 64 kbps. If you specify an scr greater than 0 and less than 64 kbps, the rate specified to the SAR is 64 kbps. |
Defaults
If you omit the pcr argument, the PVC defaults to the highest bandwidth rate queue available
(622,000 kbps). By default, the VC is configured to run as fast as possible. If you omit the oam keyword, OAM cells are not generated. If you use the oam keyword without specifying seconds, the default value of 10 seconds is used.
Command Types
Command Modes
Usage Guidelines
The atm pvc command creates a PVC and attaches it to the VPI and VCI specified. You cannot specify both vpi and vci as 0.
The VPI is an 8-bit field in the header of the ATM cell. The VPI value is unique only on a single interface, not throughout the ATM network.
The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single interface, not throughout the ATM network.
The allowed VPI and VCI ranges vary depending on the value specified by the atm vc-per-vp command. The atm vc-per-vp command sets the VCI bits, and the number of VCI bits set determines the allowable VPI range.
If you are configuring an SVC, you must use this command to configure the PVC that handles the SVC call setup and termination. In this case, specify the qsaal keyword.
The peak_rate argument determines the size of the rate queue used. ATM PVC traffic-shaping software release 50.1(1) and later and 51.1(1) and later create rate queues dynamically to satisfy the specifications of atm pvc commands. When an atm pvc command specifies a peak rate that does not match any use-configured rate queue, a rate queue is created dynamically.
The oam keyword causes the Catalyst 5000 family and 2926G series switch to generate and echo OAM F5 loopback cells to verify connectivity. After OAM cell generation is enabled, OAM cells are transmitted periodically. The remote end must respond by echoing back the cells.
The atm pvc command on the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162), the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168), and the ATM fabric integration module (WS-X5165) supports RFC 1483 Ethernet-bridged AAL5/SNAP encapsulation only.
For the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162) and the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168), and the ATM fabric integration module (WS-X5165) with ATM module Release 11.3(6)WA4(9b) and later, traffic shaping supports multiple traffic classes:
When configuring a PVC, if you enter a zero value for PCR and SCR (or do not specify any value), the channel is opened with a service type of UBR (with a maximum line rate).
While configuring a PVC, if you enter a zero value for SCR and non-zero PCR, the channel is opened with a service type of CBR at 1/PCR.
While configuring a PVC, if you enter non-zero values for PCR and SCR, the channel is opened with a service type of VBR.
|
Note The MBS should be a value between 2 and 255. If you specify an MBS of 1, the channel is opened as 1/PCR rate-shaped. |
The atm pvc command creates a PVC and attaches it to the specified VPI and VCI. The vpi and vci values cannot both be specified as 0. For example, if vpi is 0, then vci cannot be 0, and conversely, if vci is 0, then vpi cannot be 0.
The pcr, scr, and mbs arguments are only supported on the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162), the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168), and the ATM fabric integration module (WS-X5165).
Maximum pcr values are 0 to 622,000 for the ATM dual PHY OC-12 modules (WS-X5161 and WS-X5162) and the ATM fabric integration module (WS-X5165); 0 to 155,000 for the ATM dual PHY OC-3 modules (WS-X5167 and WS-X5168).
The minimum pcr or scr is 64 kbps. If you specify a pcr or scr greater than 0 and less than 64 kbps, the rate specified to the SAR is 64 kbps.
Examples
This example shows how to create a PVC to be used for ATM signaling for an SVC, using VPI 0
and VCI 5:
This example shows how to create a PVC in ATM PVC traffic-shaping software release 50.1, specifying the peak and average rates and OAM cell generation:

Related Commands
Use the client-atm-address name command to add a LANE address entry to the configuration server's database. The no form of this command removes a client address entry from the table.
Syntax Description
Defaults
The default is that no address and no ELAN name are configured.
Command Types
Command Modes
Usage Guidelines
This command binds to the specified ELAN any client whose address matches the specified template. When a client comes up, it consults the LANE configuration server, which responds with the ATM address of the LANE server for the ELAN. The client then initiates join procedures with the LANE server.
You must create the ELAN specified by the elan-name argument using the name server-atm-address command before you use the client-atm-address command.
If an existing entry in the configuration server's database binds the LANE client ATM address to a different ELAN, the new command is rejected.
This command affects only the bindings in the named configuration server database. It has no effect on the LANE components themselves.
A LANE ATM address has the same syntax as an NSAP but is not a network-level address:
LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character and an ellipsis (...) to match any number of leading or trailing characters.
In LANE, a prefix template matches the prefix explicitly but uses wildcards for the ESI and selector fields. An ESI template matches the ESI field explicitly but uses wildcards for the prefix and selector.
In our implementation of LANE, the prefix corresponds to the specific subinterface of the interface.
Examples
This example uses an ESI template to specify the part of the ATM address corresponding to an interface. This template allows any client on any subinterface of the interface that corresponds to the displayed ESI value, no matter which switch the router is connected to, to join the engineering ELAN:
This example uses a prefix template to specify the part of the ATM address corresponding to the switch. This template allows any client on the subinterface of any interface connected to the switch that corresponds to the displayed prefix to join the marketing ELAN:
Related Commands

Syntax Description
ELAN name for any LANE client MAC address or LANE client ATM address not explicitly bound to any ELAN name. The maximum length of elan-name is 32 characters. |
Defaults
The default is that no name is configured.
Command Types
Command Modes
Usage Guidelines
This command affects only the bindings in the configuration server's database. It has no effect on the LANE components themselves.
The named ELAN must already exist in the configuration server's database before this command is used. If the default name-to-ELAN name binding already exists, the new binding replaces it.

Use the lane auto-config-atm-address command to specify that the ATM address is computed automatically for the LECS or the LES and LEC, depending on whether the config keyword is used. Use the no form of this command to remove the previously assigned ATM address.
Syntax Description
Defaults
The default is that no specific ATM address or method is set.
Command Types
Command Modes
Usage Guidelines
When the config keyword is not present, this command causes the LES and LEC on the subinterface to use the automatically assigned ATM address for the LECS.
When the config keyword is present, this command assigns the automatically generated ATM address to the LECS configured on the interface. Multiple commands that assign ATM addresses to the LECS can be issued on the same interface to assign different ATM addresses to the LECS. Commands that assign ATM addresses to the LECS include lane auto-config-atm-address, lane config-atm-address, and lane fixed-config-atm-address.

Defaults
The default is automatic ATM address assignment.
Command Types
Command Modes
Usage Guidelines
If you use this command on a selected subinterface, but with a different ATM address than was used previously, it replaces the LANE client's ATM address.
A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address):
LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character and an ellipsis (...) to match any number of leading or trailing characters. The values of the characters replaced by wildcards come from the automatically assigned ATM address.
In LANE, a prefix template matches the ATM address prefix explicitly but uses wildcards for the ESI and selector fields. An ESI template matches the ESI field explicitly but uses wildcards for the prefix and selector.

Command Types
Command Modes
Usage Guidelines
This command causes the LANE client on the subinterface to use the specified ATM address (rather than the ATM address provided by the ILMI) to locate the configuration server.
A LANE ATM address has the same syntax as an NSAP (but it is not a network-level address):
LANE ATM address templates can use two types of wildcards: an asterisk (*) to match any single character and an ellipsis (...) to match any number of leading or trailing characters. The values of the characters replaced by wildcards come from the automatically assigned ATM address.
In LANE, a prefix template explicitly matches the ATM address prefix but uses wildcards for the ESI and selector fields. An ESI template explicitly matches the ESI field but uses wildcards for the prefix and selector.

Related Commands Related Command
Use the lane config database command to associate a named configuration table (database) with the configuration server on the selected ATM interface. Use the no form of this command to remove the association between a named database and the configuration server.
Syntax Description
Defaults
The default is that no configuration server is defined, and no database name is provided.
Command Types
Command Modes
Usage Guidelines
This command is valid only on a major interface, not a subinterface, because only one LANE configuration server can exist for a switch cloud.
The named database must exist before you enter the lane config database command. See the lane database command for more information.
You cannot enter multiple lane config database commands on the same interface. You must delete an existing association using the no form of this command before you can enter a new association.
Activating a LANE client requires the lane config database command and one of these commands: lane fixed-config-atm-address, lane auto-config-atm-address, or lane config-atm address.

Use the lane le-arp command to add a static entry to the LE ARP table of the LANE client configured on the subinterface. Use the no form of this command to remove a static entry.
Syntax Description
Defaults
The default is that no static address bindings are provided.
Command Types
Command Modes
Usage Guidelines
This command only adds or removes a static entry binding a MAC address to an ATM address. It does not add or remove dynamic entries. Removing the static entry for a specified ATM address from an LE ARP table does not release Data Direct VCCs established to that ATM address. However, clearing a static entry clears any fast-cache entries that were created from the MAC address-to-ATM address binding.
Static LE ARP entries are not aged and are not removed automatically.
To remove dynamic entries from the LE ARP table of the LANE client on the specified subinterface, enter the clear lane le-arp command.

Use the lane register command to register a LANE client connected by a PVC to the LANE server on the subinterface. Use the no form of this command to remove a prior entry.
Syntax Description
Virtual channel descriptor of the Server Direct PVC through which the LANE client is connected to the LANE server. |
|
Defaults
The default is that no PVC is defined, and no MAC address and ATM address are provided.
Command Types
Command Modes
Usage Guidelines
Ordinarily, SVCs are used instead of PVCs for communications within ELANs, and registration occurs dynamically via the LANE protocol. Use the lane register command only when you use PVCs.
If you use PVCs instead of SVCs for Server Direct circuits between the LANE server and LANE clients, use this command on the LANE server to identify the MAC address and the ATM address of the LANE client at the other end of a virtual circuit. If the client at the other end has a different ATM address, it is not allowed to join the ELAN.
Use the lane pvc command on a LANE client and the lane register command on a LANE server to enable PVCs, instead of SVCs alone, for LANE. The vcd value in the lane register command must match the vcd value in a lane pvc command and in an atm pvc command.
If you use PVCs for the Control Direct VCCs, you must also use PVCs for the Control Distribute VCCs. If you use PVCs for the Multicast Send VCCs, you must also use PVCs for the Multicast Forward VCCs.
Examples
This example shows how to register a LANE client connected by a PVC to the LANE server on the subinterface:

Syntax Description
Defaults
|
Note Only emulated Ethernet LANs are supported. |
Command Types
Command Modes
Usage Guidelines
The LES/BUS of an ELAN must be co-located.
The maximum length of the elan_name is 32 characters.
If you have already entered the lane server-bus command on the subinterface for a different ELAN, the LES terminates procedures with all LECs and appears as the LES for the new ELAN.
To participate in MPOA, a LEC must have an ELAN ID. The lane server-bus command enables the LEC to obtain the ELAN ID from the LES when the LEC bypasses the LECS phase.
 |
Caution If an ELAN ID is supplied, ensure that it corresponds to the same ELAN ID value specified in the LECS for the same ELAN. |
You can also enter the name elan-id command to obtain the ELAN ID from the LECS. The no form of this command removes a previously configured LES/BUS on the subinterface.
Examples
This example shows how to enable the LES/BUS for an Ethernet ELAN:

When you enter the name elan-name elan-id id preempt command to turn on higher priority LES preemption, if the primary LANE server (LES) fails, a switchover to a secondary LES occurs. But when a LES that is ranked higher in the priority list becomes active, the active LES is switched to the new LES (with the higher priority).
If you use the default configuration, the second switchover to the new LES does not occur, regardless of the priority. Use the no form of the command to turn off higher priority LES preemption.
The new-name and preempt keywords are supported in Catalyst 5000 and 2926G series ATM software release 3.2(8) and later.

Use the reload command to halt and perform a cold restart on the module.
Syntax Description
This command has no arguments or keywords.
Defaults
This command has no default setting.
Command Types
Command Modes
Usage Guidelines
The reload command halts the ATM module. If you set the ATM module to restart on error, it reboots itself. Use the reload command after you enter configuration information into a file and save to the startup configuration.
Once you have confirmed the reload, you are logged out of the session and returned to the
Console> prompt.
You cannot reload from a virtual terminal if the system is not set up for automatic booting. This restriction prevents the system from dropping to the ROM monitor and taking the system out of the remote user's control.
If you modify your configuration file, the system prompts you to save the configuration. During a save operation, the system asks you if you want to proceed with the save if the CONFIG_FILE environment variable points to a startup configuration file that no longer exists. If you say "yes" in this situation, the system goes to setup mode upon reload.
Examples
This example shows how to reload the system from the privileged EXEC prompt:
